Specification of Letters Patent.

Patented June 25,1907.

Application filed October 5,1906. Serial No. 337,657.

To CLZZ whom, it muy concern.

Be it known that I, JOHN F. HORN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Auxiliary Supports for lPrinters7 Chases and Forms, of which the following is a description, reference being had to the accompanying drawings, forming a part of this specification, in which corresponding letters of reference in the different figures indicate like parts. I

The object of my invention is to` so construct a detachable auxiliary reinforcement and support for printers chases and forms, that it may be readily applied thereto and may serve not only to reinforce the chase to prevent yielding when locking the form, but may serve to support the body of the form and prevent the same from sagging and falling out while being removed from one place to another,-all of which is hereinafter more particularly described and definitely pointed out in the claims.

In the drawings, Figure l, is a plan view of a printers chase as it would appear with a form locked therein andl showing my improved auxiliary support applied thereto, and Fig. 2, is an enlarged sectional view thereof taken upon the line 2, Fig. 1, viewed in the direction of the arrow there shown.

Referring to the drawings, u represents an ordinary printers chase having a form7 of type b locked therein in the usual way by means of wedges c. It is well known that the locking wedges tend to spread the bars of the chase, thereby permitting the type to fall out when the form is lifted. Where practicable, this may be overcome by means of the usual cross-bars which are dovetailed at the ends and adapted to fit into corresponding notches in the chase; but even this can not always be resorted to and when it is, it does not serve to directly support the type in the middle of the form. In place therefore of the single dovetailed bar, I provide a telescoping adjustable bar consisting of two elements, viz, a hollow tube d having a block or catch c rigidly attached to one end thereof, while within the opposite end of said tube is loosely fitted a rod f. A cap g is, by preference, screwed upon the end of the tube and bored to receive the rod, While a set-screwh is tapped through said cap and tube to engage the rod A block or catch i is rigidly attached to the opposite end of said rod.

Loosely mounted upon the tube d is a cross bar or fitting y', which is arranged at right angles to said tube and is provided with slots k therein for the reception of screws Z Z. A like cross-bar or fitting m is also mounted upon the rodf, which fitting is also provided with slots for the reception of like screws. Set screws n, o, are provided for temporarily securing said fittings in any predetermined position. Said fittings are caused to project downwardly from their supports sufficiently to enable the screws in the fittings to be screwed into such wooden bars or blocks p of furniture as it may be found desirable to employ in making up the form; and the object of having said fittings adjustable is to enable them to be moved to correspond to the relative positions of the furniture.

In using my improved device, the blocks e, t', are placed in the positions shown against the outer edges of the chase and the setscrew b tightened. The form is then locked in the usual way when the fittings c, m, are moved laterally to stand over such pieces of furniture asl may be found most convenient, according to the make-up of the form. The screws in the slots of the fittings are then screwed into the corresponding pieces of furniture, when the form may be lifted to the imposing'stone or elsewhere without danger of the type falling out. When so re moved to any position where the type may be supported from' beneath, the auxiliary support may be removed.

For larger forms a greater number of fittings'may be employed, but ordinarily the number shown will be found suflicien t.

I do not 'wish to be confined to the means shown for locking the telescoping elements. For example, in place of the set-screw, a pin may be employed and bores may be formed in the rod f to receive it or an eccentric clamp may be substituted.

Having thus described my invention, I claim:

1. A combined reinforcement and support for printers chases and type forms in which is combined telescoping element-s, each having a block upon its outer end to engage the edge of the chase, means for locking said telescoping elements together, and means upon said elements for detachably connecting the same with the form, whereby lateral reinforcement may be given to the chase and vertical support to the form.

2. A device of the class described, in which IOO is combined two telescoping elements, each l having a block or projection upon its outer end for engaging the edge of the chase, means for adj ustably locking said elements, and adjustable means upon said elements for connecting the same with the form.

3. A device of the class described. in which is combined a tube, a rod arranged `to telescope therewith, said` tube and rod respectively having a block or catch upon the outer end arranged at an angle thereto Jfor engaging the outer edge of the chase, means for locking said tube and rod against longitudinal movement7 adjustable cross-bars upon said rod and tube and means for detachably connecting the same with the furniture of the form.

4. In a device of the class described, the combination of a tube and rod arranged to telescope With each other, each having a catch upon its outer end arranged at right angles thereto, aset-screW for adj ustably locking said rod and tube to each other, and transverse ttings loosely mounted upon said rod and tube, said fittings having slots therein for the. reception of means for detachably engaging the furniture of the forni.

In testimonjT whereof, I have signed this specification in the presence of two subscribing Witnesses, this 2nd day of October 1906.
